[June 30, 2014]NEW YORK (Reuters) - Stock
futures were slightly lower on Monday ahead of business
activity and home sales data, with the S&P 500 and
Nasdaq Composite indexes set to close a sixth straight
quarter of gains - a streak not seen in more than 14
years.

* The Chicago Purchasing Manager Index is due to
be released at 9:45 a.m. EDT (1345 GMT) and the National
Association of Realtors will publish its pending home sales
index at 10:00 a.m. (1400 GMT).

* With an abbreviated week due to the U.S. Independence Day
holiday on Friday and a ream of data due Wednesday and Thursday,
there may be increased volatility in a market that has been
frustratingly placid for some time.

* Barring a market slide on Monday, the S&P and Nasdaq will
close up for a sixth straight quarter. That's the longest streak
of quarterly advances for the Nasdaq since 2000, while for the
S&P, it's the best run of quarters since 1998. The Dow will
close its fifth higher quarter of the last six.

* Markets will continue to keep an eye on the Middle East as
Iraqi troops battle for Tikrit after the leader of an al Qaeda
splinter group was declared caliph of a new Islamic state in
lands seized this month across a swathe of Iraq and Syria.
